How are you handling being the new Nostadramus?
Kind of worried by that. It would be good if I could predict things that were pleasant, like, I don’t know, a new praline Kit Kat or something. It’s really, really weird. Really, really, weird, obviously. The first question that a lot of people were asking me was, ‘Did you know something?’ and I didn’t. I had no idea. I had never heard anything, so it is a complete coincidence, albeit a very, very strange one.
When you wrote the episode, I guess you must have thought that such an eventuality could never happen.
Not exactly, and that was sort of the point – that it would never happen! That it was such an outrageous request on the part of the antagonist in the story. It wasn’t like I had Cameron in mind, even, I think, when writing it. I don’t think we say which party Michael Callow, our fictional PM, was from. It was quite a sympathetic portrayal of him in the episode.
No. [laughs] I didn’t see this happen.

How did you first hear about it? Did you find it on Twitter?
It was just last night, my phone just went bonkers. It was people texting me, emailing me, Twitter notifications, and this that and the other. And it took me a couple of minutes to work out what the hell was going on, because there was something involving Cameron, Black Mirror, and the Mail. And I didn’t know really what to think, so it took me a bit of clicking around to work out what on earth was happening. I thought maybe that he mentioned it? Put it this way, my mind didn’t immediately go, ‘Oh, he must have fucked a pig then?’ I was very confused. Very confused. […]

Watching the episode this morning, it feels now like the episode was written inspired from events rather than the other way round.
[does a high-pitch squeal] It’s so strange! Also, at the end of the episode his approval ratings have actually gone up slightly, so it’s not all bad. [laughs] I mean, I was asked earlier on, ‘Has this changed your opinion of David Cameron?’ and I kind of feel a bit sorry for him.
It’s such a grotesque… It’s a thing that one unnamed person has said in an unauthorised biography co-written by somebody who, by their own admission, has got a grudge against him. But it’s so irresistibly baroque and grisly that people are kind of willing it to be true. It says something that we sort of believe that it could be true. I suspect that the reality… I wonder if the reality is slightly more boring, that there were high jinks involving a pig but maybe not that. I don’t know. Pics or it didn’t happen.
There’s apparently a photo, isn’t there? You know, there’s a sequel to “The National Anthem” – a prime minister has to personally do a Jack Bauer and break into a fortified home to retrieve a photograph with his knob in a pig’s mouth. [laughs] I didn’t try to predict this!
